PADLOCK.

' Specification of Letters Patent.

Patented Sept. 6, 1921.

Applicationled April 28, 1921. Serial No. 465,109.

To all 'whom t may concern Be it known that I, CARLOS CAMPANILE, asubject of the King of Italy, residing at Ensenada, Province of BuenosAires, Ar-

5 gentina, have invented certainnew and useful Improvements in Padlocks,of'which the following is a specification.

This invention relates to lan improved padlock with'a device fordetecting and indicating when the same has been opened,

and Vhas for-one of its objects the provisionv of a padlock equippedwith a looking device SocOmbined that when operated to unlock Y yoropenthe same, a card placed within the padlock will be torn, the card beingso larthe padlock has been opened.

Another object of this invention is the provision of a padlock of theabove kind, 'provided with sight-opening,vwhich may be in the form of awindow, and a cover, whereby the card may be inspected without thenecessity of opening the padlock.

rIhe padlock according to this invention may be of any suitableitypeasregards the `locking mechanism, and either one end of the .key itself ora separate vpiece operated 4by the same may be employed to operate the'An essential feature yofthe invention conl sistsin a particular pieceoperated by the key and arranged to slide -within a guide, said piecebeing provided with one or more projections adapted -to enter into holesformed for that purpose in a. card placed within the padlock. Besides,the usual'bolt which at one end engages in a recess formed at the'endofthe shackle of the padlock, isy

operated by the aforesaid piece.

In the preferred embodimenti'the `card is secured in position bymeans ofafhinged cover', locked at one of itsV sides by the shackle of the'padlock when in 4its closed position, the lock card will be torn.

In order that the invention may be clearly understood Vand carried into:practice withoutdiiiiculty, a preferred embodiment ofthe samev has beenShown in the accompanying fillustrative drawings, wherein:-V

ing bolt 2, slidably mounted in a guide 3.

The bolt 2 tends to constantly remain in its locked position under thelaction of the spring 4 and has its locking end engaged in a notch orrecess 5, formed at the end of the shackle 6 of the padlock. The shackle6 is mounted to move on a pin 7 secured in thevcasing l.; and to insurefreedom of move-y mentand proper accommodation of the free end of theshackle to the body of the lock, the opening in the shackle for the pin7 is in the form of an elongated slot 8.

The key 9 for the lock may be arranged to directly operate the lockingmechanism, as in the case of the form shown in Figs. 1 to 7 inclusive,wherein the key passes through the ward device 10, being provided with aprojection 11 -for that purpose.

In' theV modified construction shown in Figs. 8 and 9,'i`n which the key9 is insertedthrough the front side, said key acts on a sleeve 10a intheward device which in turn by means of a suitable projection l2 operatesthe locking mechanism.

' When'turning the key to open the lock, the tooth'or projection 1l or12, according to the case, will cause the horizontal displacement of anoperating member :13 along a closure plate 20 formed with a guide slot14 in which slide two projections 15, secured to said operating member.A spring 16 tends to hold said operating member in its position of rest.After performing acertain part of itstravel, an arm 13;l on the'` member13 strikes against an arm 2 of the bolt and pushes the same along,against the action of the spring 4, whereby the bolt is disengaged fromthe recess in the shackle. This operation permits the opening of thepadlock which will be facilitated by the action exerted by the spring 17which is secured to the guide 3 and bears against the shackle end.`

The card 18 is provided with two holes 19 of suitable shape so as toexactly lit the two projections of the member in its position of rest,and is placed in the padlock in flat condition on the plate 20 whichcloses the compartment containing the locking mechanism. After the cardis positioned,

a frame 21 is brought to bear upon the card,

this frame v21 being hinged at 22 to the base of the casing 1 andprovided at its opposite side with a laterally bent flange or extendedportion 23, having .anv opening 24 through which enters the free end ofshackle 6 and also having a cut away part 25 for the reception of a noseformed on the pivoted end of said shackle.

With the parts of the padlock in 'their locked position, the shackle 6will prevent the frame 21 from being opened, so that it will beimpossible to remove the card without first unlocking the padlock Theframe 21 may be provided with a suitable sight-opening preferably closedby a glass 26, in order to be able tofsee whether the card has or. hasnot been torn, without'.

the necessity of opening the padlock. For the protection of said glass,a suitable cover 27 is secured by means of ahinge at`27, at

Y invention will be readily understood; TheV one side of the frame 21and a spring 28 is provided to normally keep the cover in its closedposition. The cover 27 is formed with vlaT-projection 29 Vto facilitatethe opening thereof. If

desired, the cover may also be provided with a suitable fastening pin,adapted to be inserted into the easing and Aengage in a recess formed inthe part 13 in such a way that by a slight movement of Ythe key it maybe released. i Y l From the foregoing description, the lop-1 eration ofthe padlock accordingvto this card being provided with a signature orother means of definite identification and itsv removal from the padlockonly being possible after the latter its proper key, it will one can atany time determine whether the padlock has been opened and if suchopening has been effected by the persons possessing the` key. 1 i

has been opened byA at once be seen thatV It will be evident thatseveral modifications ofconstruction and .detail may be in.VV

troduced without departing vfrom the scope of this invention, as clearlydefined in the vclaims hereto annexed.L Y
